Help me understand why anyone would spend the extra money ($450 and up) on a Kestrel with a built in ballistics solver when you can buy a basic weather meter for $100 (like the WeatherFlow) and pair it to a ballistics app like Geoballistics, 4DOF or AB? No hate or anything, I legitimately want to know what I would be missing? Am I overlooking something? I know it's convenient to have it all in one device but, that seems like relatively small thing especially when considering the Kestrel hardware requires a bunch of button pushing and lacks the benefits of a smartphone touch screen.
